From 23ae0c17b89cfeb511aa0770735a319d35597072 Mon Sep 17 00:00:00 2001 From: Richard Henderson Date: Mon, 10 Feb 2020 13:00:15 +0000 Subject: [PATCH] random: Make RANDOM_TRUST_CPU depend on ARCH_RANDOM Listing the set of host architectures does not scale. Depend instead on the existence of the architecture rng. This will allow RANDOM_TRUST_CPU to be selected on arm64. Today ARCH_RANDOM is only selected by x86, s390, and powerpc, so this does not adversely affect other architectures.
